I'm hoping this is the correct place for this post. Was looking for a quest category on the main forums. So I have a 2004 Nissan Quest and having problems with the front a.c.. The back a.c. is working but the front is not engaging at all. Also the motor speed only works on max speed. Which I'm assuming the blower motor resistor. Also the controls to change the air temperature is not working at all. So does this sound like one problem with just the resistor or many different problems?
